Custom Hot Rod with a DOHC LS7

This custom hot rod called 69Ultra was built by Slicks Garage in Miami, Florida. The project started with the last of Slicks limited edition Ultra fiberglass body. The design is Slicks Garage homage to hot rodding and includes details from many influential decades. This car is incredible lucky to be powered by a 7.0 L LS7 with Mercury Racing SB4 DOHC heads. The heads feature a 43.25 mm intake valve, 35.0 mm exhaust valve, and 4 valve per cylinder. The exhaust flange shape is the same as a stock LS3 with a +0.3 degree tipped-out angle. The bolt hole locations are 1.82 inches lower and 0.53 inches further out. To give you an idea of how much a combo like this would cost, Slicks Garage says it would be around $169,000.
